Marcio,
The dates you mentioned are transactional data, not configuration. These dates are typically generated through Shipment and Delivery scheduling.
This is not an MM topic, you have posted this question in the wrong forum.
For the functional description of Transportation scheduling, see Transportation and Delivery Scheduling - Shipping in Series Sales and Distribution - SAP Library
Each event (date) that you mentioned can be configured in various places in SPRO. In general, the appropriate transactions are found within SPRO > IMG > Logistics Execution > Shipping > Basic shipping functions.
Best Regards,
